The
AT&T Hobbit is a
microprocessor design that
AT&T Corporation developed in the early 1990s. It was based on the company's
CRISP (C-language Reduced Instruction Set Processor) design, which in turn grew out of
Bell Labs'
C Machine design of the late 1980s. C Machine, CRISP and Hobbit were optimized for running the
C programming language. The design concentrated on fast instruction decoding, indexed array access and
procedure calls. Its processor was partially
RISC-like. The project ended in 1994 because the Hobbit failed to achieve commercially viable sales.
